The 2022 Paralympic Winter Games will run from March 4-13, and each day, NBCOlympics.com will recap the biggest stories that happened overnight. Here's what you may have missed from the seventh day of Paralympic competition.

Brenna Huckaby leapfrogged three Chinese riders with a massive second run in the banked slalom SB-LL2 to claim gold, Team USA's fourth overall of the 2022 Paralympics and her second medal since earning bronze Monday in snowboard cross. The mother of two daughters was initially in disbelief upon crossing the finish line, asking if she was on the podium. When the camera finally caught up to her she was already smiling, and she proceeded to thank her family and dedicate the performance to them.

A double Paralympic gold medalist in 2018 and a four-time world champion, Huckaby nearly missed the 2022 Games after her SB-LL1 classification was removed from the women's program due to a lack of athletes. A subsequent legal ruling permitted her to take part, but with the caveat of "competing up" to SB-LL2, essentially at a disadvantage. Because of this, her victory isn't technically a title defense – but the 26-year-old is nevertheless a repeat champion in the banked slalom discipline.

Huckaby was one of three women's SB-LL2 riders to dip below 78 seconds on the course. The others, 17- and 18-year-olds Geng Yanhong and Li Tiantian of China, took silver and bronze. Huckaby's teammate and PyeongChang silver medalist Brittani Coury, a nurse and EMT who has helped care for COVID-19 patients during the pandemic, finished ninth. She was there to greet Huckaby after she won.

"I still can’t believe I won because those girls [from China] are freaking fast," said Huckaby, the only non-Chinese rider in the top five. "I also know that I can be fast, and so I was like if I can just ride my snowboard like I know how to do, I can be in the running."

During the first set of runs in the men's banked slalom SB-UL, French snowboarder and taekwondo practitioner Maxime Montaggioni was stripped of his lead by just a hundredth of a second after 19-year-old Ji Lijia of China put down a 1:09.86. But the reigning world champion laid down the gauntlet on his second run to clock a 1:09.41, which ultimately held for gold. Ji fronted a Chinese sweep of the SBX event on Monday. Defending gold medalist Mike Minor of the U.S. finished eighth.

"At the gate, I had nothing to lose. It was 0.01 and I couldn't think that I will lose," Montaggioni said. "I had to do everything I could to leave the competition with no regrets. So I was free and strong, and it paid off. So for me it was the perfect situation."

Americans Noah Elliot and Mike Schultz, the men's SB-LL1 gold and silver medalists in PyeongChang, just missed the event's podium in fourth and fifth. Snowboard cross bronze medalist Wu Zhongwei won gold. In the men's SB-LL2, Wu's compatriot and 2019 world champion Sun Qi was the victor, trailed by Finn Matti "The Sledgehammer" Suur-Hamari, one of three riders from different nations donning helmets featuring a picture of a unicorn in honor of their late shared coach Mikko Wendelin.

China dominated snowboarding, winning three of the eight events and earning 10 of the 24 medals; a comparable showing to that of Team USA's in 2018, when the Americans won three of five titles and took home seven of 15 medals.

Americans Oksana Masters and Kendall Gretsch captured sitting gold and silver in the 12.5km individual on the final day of biathlon, reversing the order in which they went one-two in Tuesday's middle-distance race and giving the duo their third shared podium of three events in the sport classification, having also placed a respective first and third in last week's 6km sprint.

Masters missed the last shot of her third shooting bout — up until then she'd been perfect throughout the 2022 Paralympics — and trailed Gretsch after the 10km mark. But the legendary skier shot clean in her fourth trip to the range and dug deep over the final 2.5km to triumph under the lights, upgrading a 2018 silver in the event for her second title and fifth medal of the Games.

"I was just trying to channel my inner Kendall [Gretsch]," Masters said. "I knew it was going to be tough and I just wanted USA to be one-two and I can't wait to celebrate this."

Gretsch, the two-time reigning world champion, hit all 20 targets to complete a medal trifecta at the Games, while sprint silver medalist Shan Yilin of China also shot clean to grab bronze. Despite being perfect with her rifle for the first time at these Paralympics, 2017 world champion Anja Wicker of Germany, bronze medalist in the 10km, finished fourth.

Ukraine was unable to land another podium sweep, coming about 20 seconds short of a third straight in the men's vision impaired classification, though it still managed to find more hardware, concluding biathlon competition with 22 of the possible 54 medals, slightly more than 40%.

Double world champion in the event Liudmyla Liashenko led the women's individual standing from start to finish to also complete a medal trifecta, while her Ukrainian teammates Oksana Shyshkova and Oleksandr Kazik both struck gold themselves in the vision impaired classes alongside respective guides Andriy Marchenko and Serhii Kucheriavyi. Shyshkova's gold was No. 5 of the Games with three in biathlon and two in cross-country. Behind Kazik and Kucheriavyi in the men's VI race were Vitaliy Lukyanenko and guide Borys Babar, gold medalists in the previous sprint and middle-distance events.

In the men's sitting event, 10km titlist Liu Mengtao of China added another gold for medal No. 3 of the Games, and Ukraine's Taras Rad also made his third podium with silver. Liu Mengtao's teammate and sprint winner Liu Zixu took bronze. Americans Dan Cnossen and Aaron Pike, respective silver medalists at the 2018 Paralympics and most recent world championships, finished seventh and ninth. In the men's standing, double world champion Benjamin Daviet of France redeemed a 2018 runner-up finish to defending gold medalist Mark Arendz of Canada, scoring a gold for his second of the Games after a cross-country sprint title on Wednesday.

It will be USA vs. Canada for gold once again in sled hockey after both North American nations logged 11-0 semifinal victories over teams from Asia.

Team USA, the three-time defending Paralympic gold medalists dismissed host nation China thanks to strong performances from its two stars. 

Declan Farmer and Brody Roybal combined to open the scoring halfway through the first period with a play straight off the soccer field. Farmer flipped a tight-angle shot over the Chinese goaltender’s shoulder but instead of finding the net, he found the helmet of Roybal who “headed” it into the goal.

Less than a minute later, Farmer again found Roybal – intentionally this time – for a shorthanded goal to make it 2-0. A third Farmer assist, this time to Joshua Misiewicz, grew the U.S. lead to 3-0, then in the final minute of the opening frame, Roybal completed his first-period hat trick off a fourth assist from Farmer as the U.S. took a 4-0 lead into the intermission.

Roybal would later add two assists and a fourth goal, and Farmer pitched in a pair of goals himself as the U.S. improved its goal difference to 25-1 on the tournament.

REPLAY

In the first semifinal game, No. 2 seed Canada delivered an 11-0 victory of its own over South Korea, putting 43 shots on goal to nearly double the score of the two teams' previous 6-0 preliminary matchup. Forwards Tyler McGregor and Billy Bridges respectively scored four and three times. Canada is now 36-0 against South Korea in sled hockey.

The U.S. and Canada will meet to decide a global championship for the sixth consecutive time.

China and South Korea face off Saturday in the bronze medal game.

China and Sweden won their semifinal matchups, both redeeming round-robin loses to the teams, to set up a repeat of the most recent world championship final in Saturday's gold medal game. The Chinese defeated the Swedes 5-3 at the 2021 World Wheelchair Curling Championship, also held on home ice for the Chinese.

In the semifinal between Sweden and Slovakia, each 7-3 in round-robin play, Sweden produced a point in each of the first three ends. Slovakia tied it up in the fourth, 3-3, by tucking stones behind guard before executing a perfect hit.

The teams traded points in the fifth and sixth ends before Sweden stole in the seventh on an over-curled double attempt by Slovakia to make it 5-4. Slovakia over-curled again in the eighth while going for two, giving up another steal to Sweden and the 6-4 victory.

Meanwhile, the other semifinal wasn't as close between China and Canada – the only two nations to have won gold in wheelchair curling since its Paralympic debut in 2006. Defending gold medalist and reigning world champion China scored first, after which Canada, gold medalist in 2006, 2010 and 2014, leveled in the second.

China played an open draw for three in the third, Canada countered with a draw of its own to score two in the fourth, and then China made a hit for another three in the fifth to go up 7-3. The sixth included perhaps the dagger for Canada which botched a take-out and gave China a 9-3 lead. Two in the seventh for Canada wasn't enough and China won 9-5.

In the bronze medal game which took place later in the evening, Canada defeated Slovakia 8-3. The bronze medal is Canada's fifth wheelchair curling medal in five editions of the sport at the Winter Paralympics.

Three sisters from Austria secured medal positions in the women's giant slalom vision impaired. A quick glance at the results might only show two, but a third serves a guide for her sibling on the slopes. Veronika Aigner, 19, along with guide and older sister Elisabeth Aigner won gold, and reigning world champion Barbara Aigner, 16, took bronze.

Veronika and Elisabeth together posted the fastest times of both runs, 54.08 and 58.46, to win by more than seven seconds. Barbara, meanwhile, recorded the third- and second-best times. China's Zhu Daqing fell hard while crossing the finish on her first run, yet somehow returned to put down a good enough second run to hold second place for silver.

The Aigners are not just sisters — Barbara has a twin brother, Johannes Aigner, who has been an absolute superstar these Games. So far the 16-year-old has won downhill gold, super-G bronze, super combined silver and giant slalom gold with Sunday's slalom event still remaining.

Another Austrian Elina Stary, the 2022 Games' youngest competitor at 15 years old, finished just off the podium in fourth. In an early stunning result, three-time defending gold medalist Henrieta Farkasova of Slovakia had an issue on her first run with guide Michal Cerven and DNF'd.
